To all whom it may concern:

Be it known that I, EMILE JOHN WELF- FENS, a subject of the King of the Belgians, residing at 50 Duncan Road, Longsight,

Manchester, .in. the county of Lancaster,

England, have invented new and useful Improvements Relating to Swing Gearing for Slubbing, Roving, and like Frames, of which the. following is a. specification. I

The invention relates to swing gearing for slubbing,'roving andlike frames.

It aims at securing renitent lateral ,constraint in spring loaded swings as described in British Patent No. 130549, at providing easy means for adjusting and maintaining the thrust-arm of such swings inposition, and at :constructions securing automatic lubrication of the mechanism in an efiicient and economical manner. j V

The invention is explained with reference to the accompanying drawings, diagrammatic, but clearly showing the principles nor; Tubes 19,20 and 21 conduct'the lu-i involved. Referring tothe drawings- Figure 1 shows. a sectional plan, and v Figure 2 an elevation of the rail box and the members it carries and contains;

Figure 3 is an elevation and Figure l is a planshowing the thrustarm, the thrust spring and as much ofthc spring-bracket as required for elucidation. Figure 5 is a section through the thrust arm boss upon which the driven chain wheelrevolves; a

Figure 6 is a development showing the arrangement of oil holes and oil grooves in that boss;

Figure 7 shows the spring used to secure renitent lateral constraint, automatic compensation for lateral wear, oil retention and elimination of chatter;

Figure 8 shows in elevation, and

Figure 9 shows in planand section plan, the member upon which the thrust-arm rests and slides to and fro; i

Figure 10 is a partial elevation and v Figure 11 a sectional side view of the driven chain wheel given to show the-coustruction of the jaws which grip the coin necting p1ate'.

Figure 12 1s a side elevation, partly in section, showing the invention applied to a flier frame, parts being illustrated in? dotted lines. i V Figure13 is a plan View of'the' same.

In Figures 1 and 2, numeralvv 1 designates the rail box. Spur wheel 2 is fixedto front bobbin shaft 3,'that shaft rotating in bean ings 4311(15. Spur wheel 6 rotates in bear} ing 7 and is fixed to back bobbin shaft t}.

. The rectangular plate 9 slides in jaws on" spur wheel" 6 and on. chain wheel 10, these i jaws engage the plate .9 zit-790 and constitute, wi th the plate, the Oldham coupling that connects WheelsIGand 10 for'rotation. Chain wheel 10 rotateson the boss of thrust; arm 11,. theboss end o-f that arm resting and sliding upon member 12. Memberwlfl forms a bearing for shaft 8 and oscillates in bearing 13. Spring 14 exerts lateral pressure, and is loose around member 12.

Multiple drip lubricator 1 5, with its lid 16 is fixed to rail box 1 by bolt 17, which also fixesrack 18, or inany, other suitable mhn bricant respectively tobearing. 5, to spur wheels 2'and 6 land to hearing 13. Needles '22, 23 and 2 1 in the foregoing tubes, regu-.

late the flow oflubricant.

Having designated the component parts, 2

their action will be explained whererel evant. Spring 14: constrains frenitently, components9, 10, 11 and 12, thereby avoiding the rigidity otherwise required to keep them in position. It provides automatic compensation for lateral wear-in these components whilst allowing lateral freedom of motion. Its lateral pressure prevents the escape of lubricant-whilst creatingthe slight drag'required to avoid. chatter when plate 9 becomes easy in the jaws on wheelst and 10. r

Theshouldered threaded stud 25, with looking nut 26, screws adjustably in thrustarm 11 and engages a slot 27 provided in spring bracket 28, see Figures Sand A" central. line through the slot 27 coincides with thelaxis of; the driving shaft A and consequently stud 25 remains in a line with the axis of the drivingv shaft and constitutesfan unconstrained center of oscillation for the thrust arm 11. The 'circularportion of arm 11. engaged by spring 29 is Y slightly taper, thereby spring action forces the arm and consequently the shoulder of stud 25 against bracket 28, and by adjusting stud 25 we may position arm 11 so that the axis, of its boss will be maintained parallel or coincident with the axis of shaft 8 during operation whilst avoiding rigid connections between the moving and the stationary parts of the machine.

Automatic lubrication obtains in an efiicient, waste avoiding manner. External oiling of plate 9 and of the jaws in which it, reciprocates is unsatisfactory. The centrifugal action of the mechanism throws the oil. Lubrication effected from the inside harnesses the-centrifugal action to further etiiciency. Action is as follows (a) BackshafL-Tube 21 conducts oil through bearing 18, through hole 30 in member 12 (see Figures 1 and 8) to chamber 31 (see Figures 1 and 8), andto shaft 8. A groove at the bottom of the bore in 12 conducts the oil from chamber 31 to void created by ho-llowplate 9 between 6 and 10, andso through grooves 32 to recesses 33 in the jaws on members 6 and 10 (see Figures 1. 2,9 and 10). Plate 9 and wheels 6 and 10 are so arranged that the oil is retained in all relative positions of 6, 9 and 10, centrifugal action effecting the required distribution.

The movement of alternate vertical translation of box 1 causes relative displacement of jaws 6 and plate 9 with regard to 10, both wheels remaining connected for rotation by plate 9, it oscillates arm 11 and causes that arm to slide to and fro 01112 and it oscillates 12 in 13. The needle 24- provided in 12 (see Figures 1, 7 and 8) allows the oil to run in the oil well 35 of bosson arm 11 (see Figure 5) when oscillation inclines. 12 in either direction. Well 35 is kept closed by member 12 (see Figuresl, 7 and 8). From that well the bearing of wheel 10 is lubricated through lower holes and groove-in jaws of arm 11 shown developed in Figure 6, the oil return ing to the well through upper holes. Any surplus of lubricant in void between 6 and 10 or in well 35 flows from oneto the other through hole 43. Holes 36 and 37 (see Figures 1 and 10) conduct, through centrifugal action, part of the oil in bore of wheel 10 to the chain 100, and thechain in itsturn lubricates the teeth on both its wheels 10 and 101.

Part of the'lubricant conducted contacts with shaft 8 provided with a spiral groove 38. that groove conducting the oil through hole-39 in boss of wheel 6 (see Figure 1) to chamber 40 in hearing The presence of oil;,lubricates shaft 8 and its bearing in'12, and the certain amount of oil thrown through window 8% and in void between wheels 6 and 10 furthers lubrication. I

(5) Front shaft. Tube 19 conducts oil to chamber 41in bearing-5 and the groove in shaft 3 in its turn conducts oil to chamber 42 in bearing 4, the boss of wheel 2 fitting suiliciently close between at and 5 to avoid waste.

(0) W heel tecth.-Tube 20 causes oil to flow on wheels 2 and 6 and so secures lubrication of their teeth.
